I believe you are not getting all of my messages (I cannot exactly see them
since I am using Gmail and Gmail blocks the messages I send to mailing
lists). Anyway, the WM_USER + 1 is hard coded:
I traced the bug to here:
function TIcsWndHandlerPool.GetWndHandler(
HandlerCount : UINT;
ThreadID : THandle) : TIcsWndHandler;
var
I : Integer;
L : TIcsWndHandlerList;
begin
// Search the list which has same thread ID
I := FList.Count - 1;
while (I >= 0) and
(TIcsWndHandlerList(FList.Items[I]).ThreadID <> ThreadID) do
Dec(I);
if I >= 0 then
L := TIcsWndHandlerList(FList.Items[I])
else begin
// No list found. Create a new one
L := TIcsWndHandlerList.Create;
L.ThreadID := ThreadID;
FList.Add(L);
end;
// Search the list for a WndHandler with enough MsgHandlers available
I := 0;
while I < L.Count do begin
Result := TIcsWndHandler(L.Items[I]);
if Result.GetMsgLeft >= HandlerCount then
Exit;
Inc(I);
end;
Result := TIcsWndHandler.Create;
Result.FOwnerList := L;
OutputDebugString(PChar('TIcsWndHandler.Create OwnerList = ' +
IntToHex(Integer(Result.FOwnerList), 8)));
Result.MsgLow := WM_USER + 1; // The EIP comes here, does not use my
wndhandler in thread!
L.Add(Result);
end;
This occurs in threadattach in the thread code I sent!
Best Regards,
SZ
